The VRGE generates validation rules that are derived according to
Table 1, and each AS has a VRGE. The VE loads validation rules
generated by VRGE to filter packets passed between ASes (in the case
of Figure 3, from neighboring ASes into AS-1). In the SAVA testbed,
the VE is implemented as a simulated layer-2 device on a Linux-based
machine inserted into the data path just outside each ASBR interface
that faces a neighboring AS. In a real-world implementation, it
would probably be implemented as a packet-filtering set on the ASBR.
The AS-IPv6 prefix mapping server is also implemented on a Linux
machine and derives a mapping between an IPv6 prefix and the AS
number of that prefix.

It is intended that eventually the SAVA testbed will be implemented
directly on the CNGI-CERNET2 backbone, but in the early stages the
testbed has been implemented across 12 universities connected to
CNGI-CERNET2. First, this is because some of the algorithms need to
be implemented in the testbed routers themselves, and to date they
have not been implemented on any of the commercial routers forming
the CNGI-CERNET2 backbone. Second, since CNGI-CERNET2 is an
operational backbone, any new protocols and networking techniques
need to be tested in a non-disruptive way.

|<-------------------------------------------------------|
| |
| EAP-Response/Identity |
| (Includes user's Network Access Identifier, NAI) |
|------------------------------------------------------->|
| +--------------------------------------------------+
| | Server determines the network name and ensures |
| | that the given access network is authorized to |
| | use the claimed name. The server then runs the |
| | AKA' algorithms generating RAND and AUTN, and |
| | derives session keys from CK' and IK'. RAND and |
| | AUTN are sent as AT_RAND and AT_AUTN attributes, |
| | whereas the network name is transported in the |
| | AT_KDF_INPUT attribute. AT_KDF signals the used |
| | key derivation function. The session keys are |
| | used in creating the AT_MAC attribute. |
| +--------------------------------------------------+
| EAP-Request/AKA'-Challenge |
| (AT_RAND, AT_AUTN, AT_KDF, AT_KDF_INPUT, AT_MAC)|
|<-------------------------------------------------------|
+------------------------------------------------------+ |
| The peer determines what the network name should be, | |
| based on, e.g., what access technology it is using. | |
| The peer also retrieves the network name sent by | |
| the network from the AT_KDF_INPUT attribute. The | |
| two names are compared for discrepancies, and if | |
| necessary, the authentication is aborted. Otherwise,| |
| the network name from AT_KDF_INPUT attribute is | |
| used in running the AKA' algorithms, verifying AUTN | |
| from AT_AUTN and MAC from AT_MAC attributes. The | |
| peer then generates RES. The peer also derives | |
| session keys from CK'/IK'. The AT_RES and AT_MAC | |
| attributes are constructed. | |
+------------------------------------------------------+ |
| EAP-Response/AKA'-Challenge |
| (AT_RES, AT_MAC) |
|------------------------------------------------------->|
| +-------------------------------------------------+
| | Server checks the RES and MAC values received |
| | in AT_RES and AT_MAC, respectively. Success |
| | requires both to be found correct. |

| | mechanism. |
| GSS_C_MA_MECH_PSEUDO | Indicates that a mech is a |
| | pseudo-mechanism. |
| GSS_C_MA_MECH_COMPOSITE | Indicates that a mech is a composite of |
| | other mechanisms. This is reserved for |
| | a specification of "stackable" |
| | pseudo-mechanisms. |
| GSS_C_MA_MECH_NEGO | Indicates that a mech negotiates other |
| | mechs (e.g., SPNEGO has this |
| | attribute). |
| GSS_C_MA_MECH_GLUE | Indicates that the OID is not for a |
| | mechanism but for the GSS-API itself. |
| GSS_C_MA_NOT_MECH | Indicates that the OID is known, yet it |
| | is also known not to be the OID of any |
| | GSS-API mechanism (or of the GSS-API |
| | itself). |
| GSS_C_MA_DEPRECATED | Indicates that a mech (or its OID) is |
| | deprecated and MUST NOT be used as a |
| | default mechanism. |
| GSS_C_MA_NOT_DFLT_MECH | Indicates that a mech (or its OID) MUST |
| | NOT be used as a default mechanism. |
| GSS_C_MA_ITOK_FRAMED | Indicates that the given mechanism's |

| | framed as per Section 3.1 of [RFC2743]. |
| GSS_C_MA_AUTH_INIT | Indicates support for authentication of |
| | initiator to acceptor. |
| GSS_C_MA_AUTH_TARG | Indicates support for authentication of |
| | acceptor to initiator. |
| GSS_C_MA_AUTH_INIT_INIT | Indicates support for "initial" |
| | authentication of initiator to |
| | acceptor. "Initial authentication" |
| | refers to the use of passwords, or keys |
| | stored on tokens, for authentication. |
| | Whether a mechanism supports initial |
| | authentication may depend on IETF |
| | consensus (see Security |
| | Considerations). |
| GSS_C_MA_AUTH_TARG_INIT | Indicates support for initial |
| | authentication of acceptor to |
| | initiator. |
| GSS_C_MA_AUTH_INIT_ANON | Indicates support for |
| | GSS_C_NT_ANONYMOUS as an initiator |
| | principal name. |
| GSS_C_MA_AUTH_TARG_ANON | Indicates support for |
| | GSS_C_NT_ANONYMOUS as a target |
| | principal name. |
| GSS_C_MA_DELEG_CRED | Indicates support for credential |
| | delegation. |
| GSS_C_MA_INTEG_PROT | Indicates support for per-message |
| | integrity protection. |

| Message Type | Purpose |
+----------------------+--------------------------------------------+
| NORM_DATA | Sender message for application data |
| | transmission. Implementations MUST |
| | support at least one of the |
| | NORM_OBJECT_DATA, NORM_OBJECT_FILE, or |
| | NORM_OBJECT_STREAM delivery services. The |
| | use of the NORM FEC Object Transmission |
| | Information header extension is OPTIONAL |
| | with NORM_DATA messages. |
| NORM_CMD(FLUSH) | Sender command to excite receivers for |
| | repair requests in lieu of ongoing |
| | NORM_DATA transmissions. Note the use of |
| | the NORM_CMD(FLUSH) for positive |
| | acknowledgment of data receipt is |
| | OPTIONAL. |
| NORM_CMD(SQUELCH) | Sender command to advertise its current |
| | valid repair window in response to invalid |
| | requests for repair. |
| NORM_CMD(REPAIR_ADV) | Sender command to advertise current repair |
| | (and congestion control state) to group |
| | when unicast feedback messages are |
| | detected. Used to control/suppress |
| | excessive receiver feedback in asymmetric |
| | multicast topologies. |
| NORM_CMD(CC) | Sender command used in collection of |
| | round-trip timing and congestion control |
| | status from group (this is OPTIONAL if |
| | alternative congestion control mechanism |
| | and round-trip timing collection is used). |
| NORM_NACK | Receiver message used to request repair of |
| | missing transmitted content. |
| NORM_ACK | Receiver message used to proactively |
| | provide feedback for congestion control |
| | purposes. Also used with the OPTIONAL |
| | NORM Positive Acknowledgment Process. |
+----------------------+--------------------------------------------+
+-----------------------+-------------------------------------------+
| Message Type | Purpose |
+-----------------------+-------------------------------------------+
| NORM_INFO | Sender message for providing ancillary |
| | context information associated with NORM |
| | transport objects. The use of the NORM |
| | FEC Object Transmission Information |
| | header extension is OPTIONAL with |
| | NORM_INFO messages. |
| NORM_CMD(EOT) | Sender command to indicate it has reached |
| | end-of-transmission and will no longer |
| | respond to repair requests. |
| NORM_CMD(ACK_REQ) | Sender command to support |
| | application-defined, positively |
| | acknowledged commands sent outside of the |
| | context of the bulk data content being |
| | transmitted. The NORM Positive |
| | Acknowledgment Procedure associated with |
| | this message type is OPTIONAL. |
| NORM_CMD(APPLICATION) | Sender command containing |
| | application-defined commands sent outside |
| | of the context of the bulk data content |
| | being transmitted. |
| NORM_REPORT | Optional message type reserved for |
| | experimental implementations of the NORM |
| | protocol. |
+-----------------------+-------------------------------------------+
+-----------------------+----------+--------------------------------+
| Command | Sub-type | Purpose |
+-----------------------+----------+--------------------------------+
| NORM_CMD(FLUSH) | 1 | Used to indicate sender |
| | | temporary end-of-transmission. |
| | | (Assists in robustly |
| | | initiating outstanding repair |
| | | requests from receivers). May |
| | | also be optionally used to |
| | | collect positive |
| | | acknowledgment of reliable |
| | | reception from a subset of |
| | | receivers. |
| NORM_CMD(EOT) | 2 | Used to indicate sender |
| | | permanent end-of-transmission. |
| NORM_CMD(SQUELCH) | 3 | Used to advertise sender's |
| | | current repair window in |
| | | response to out-of-range NACKs |
| | | from receivers. |
| NORM_CMD(CC) | 4 | Used for GRTT measurement and |
| | | collection of congestion |
| | | control feedback. |
| NORM_CMD(REPAIR_ADV) | 5 | Used to advertise sender's |
| | | aggregated repair/feedback |
| | | state for suppression of |
| | | unicast feedback from |
| | | receivers. |
| NORM_CMD(ACK_REQ) | 6 | Used to request |
| | | application-defined positive |
| | | acknowledgment from a list of |
| | | receivers (OPTIONAL). |
| NORM_CMD(APPLICATION) | 7 | Used for application-defined |
| | | purposes that need to |
| | | temporarily preempt or |
| | | supplement data transmission |
| | | (OPTIONAL). |
+-----------------------+----------+--------------------------------+
+--------------------+-------+--------------------------------------+
| Flag | Value | Purpose |
+--------------------+-------+--------------------------------------+
| NORM_FLAG_CC_CLR | 0x01 | Receiver is the current limiting |
| | | receiver (CLR). |
| NORM_FLAG_CC_PLR | 0x02 | Receiver is a potential limiting |
| | | receiver (PLR). |
| NORM_FLAG_CC_RTT | 0x04 | Receiver has measured RTT with |
| | | respect to sender. |
| NORM_FLAG_CC_START | 0x08 | Sender/receiver is in "slow start" |
| | | phase of congestion control |
| | | operation (i.e., the receiver has |
| | | not yet detected any packet loss and |
| | | the "cc_rate" field is the |
| | | receiver's actual measured receive |
| | | rate). |
| NORM_FLAG_CC_LEAVE | 0x10 | Receiver is imminently leaving the |
| | | session and its feedback SHOULD not |
| | | be considered in congestion control |
| | | operation. |
